Publication number: 20150090284Abstract: A cigarette paper contains pulp fibers and filler particles, whereby at least 20% of the filler particles, by mass or by particle number, have a flaked shape. The flaked filler particles have a length l, a width b and a thickness d, which correspond to the respective maximum extension in three mutually orthogonal spatial directions, whereby the length l as well as the width b are at least twice as large as the thickness d. The mass-specific median value d50 of the particle size distribution measured according to ISO 13317-3 is between 0.2 ?m and 4.0 ?m, and the flaked particles are formed by calcium carbonate.Type: ApplicationFiled: November 25, 2014Publication date: April 2, 2015Inventors: Dieter Möhring, Roland Zitturi, Dietmar Volgger

Publication number: 20150083148Abstract: A smoking article includes a sheet material including a fibrous layer formed of cellulosic fibres and at least 50% by weight of inorganic filler material having a particle size in range of from 0.1 microns and 50 microns, wherein the sheet material has a tensile strength of at least 900 N/m. The fibrous layer includes a binder material, such as an organic binder material. The organic binder material can be a cellulosic binder material. A coating layer may be provided on at least one side of the fibrous layer.Type: ApplicationFiled: December 1, 2014Publication date: March 26, 2015Inventors: Laurent POGET, Alexandre MALGAT, Christoph SORG, Andreas HOFENAUER, David CROLL, Rolf GERICKE

Publication number: 20150040932Abstract: A tobacco product is formed by rolling moistened tobacco leaves about a cylindrical form casing and allowing the leaves to dry to form a shell. After the form casing is removed a consumer can fill the shell with crushed tobacco leaves of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product.Type: ApplicationFiled: July 22, 2014Publication date: February 12, 2015Inventor: Daniel S.

Patent number: 8950409Abstract: A tobacco smoking mixture and/or a cigarette wrapper with high-temperature ammonia-release agents therein are provided, wherein the high-temperature ammonia-release agents are present in an amount effective to reduce the cytotoxicity of gas phase or particulate matter formed during smoking of the cigarette. The high-temperature ammonia-release agents are capable of reducing the cytotoxicity of gas phase or particulate matter by evolving ammonia at temperatures greater than about 200° C., wherein the ammonia can interact with the particulate matter. Additionally, the high-temperature ammonia-release agents can be formed by heating an aqueous mixture of an iron precursor compound, an ammonia source compound and an acid.Type: GrantFiled: January 23, 2012Date of Patent: February 10, 2015Assignee: Philip Morris USA Inc.Inventors: Jay A Fournier, John B. Paine, Douglas A. Fernandez
